How about Jonny?! Thats a kick ass name ;)

nice.. im not too good with names.. can't help you.. Akuma is good (thank you ppl who posted comments before me!)

How about you name him ' Deruku' it's jap. for dark!.. O.o; i think

again, very good! Oni or Akuma (i lik Akuma better) they both mean devil.

Nice. ^-^ Hmm. How 'bout Nicademus? (I don't think that's how it's spelled though...)
